thanks

Yep, that made sense.
That info also helped me find some online tutorials.
Sweet.
Thanks for taking the time to explain that,

If I pull out these flappers, what would I tell my mechanic about how to retune the engine?

On the drivers side below the steering wheel, there is a obd2 connector= (onboard diagnose) connector. For tech to plug in their IDS computer= (intergrated diagnose system) computer, to figure out codes & run programs with. A Xcal3 by SCT is a flasher that you plug into the obd2 connecter & reflashs the pcm(power conrol modu.) By reflashing the pcm is like= in old cars w/ carbs/distubiters, where you change the timing by turning the dist. either advance or retarding it & recurving it w/ lighter or heavier springs for how fast & how slow you want the timing to come in. And you also have how far you want the curve to come in to. And then there is the carb to adjust. I think you got the just of it. The factory has set the pcm up for a very broad range for a lot of different drivers. A tuner= a flasher makes your car so much more drivable= a lot smoother than you can think. Say like a electric r/c car w/ a electronic speed control= one has steps ever 500 & the better one has them ever 1000 times. The one w/ more steps is going to be a lot more lineier or smoother than the one w/ less steps. So you buy the sct xcal3 & plug it in & down load the tune your self in a few minutes. It pulls the oem out 1st & then downloads the new & improved one. I hope that helps you. Oh & if you have issues w/ the imrc= tumble flaps, (you'll need to remove them & then you'd need a tune for that) >>>or replace the manifold w/ a new one, which is 'bout $200.<<<

The regular fuel tune is a waste as most of the performance comes from the premium fuel tune. 2.00-4.00 a tank is worth it. Do you or are you going to add a header?

Yeah... 2.0's have the tumble flaps.. I had an 07 ZX3 SES and the flaps went bad... fortunately it just threw a lot of bits of plastic and not any metal.. dealer cleaned it all out and replaced with another manifold. Ran fine after that. I even got a nice little bump in MPG. I think IMRC's help with low end throttle response and MPG... that is what they are designed for.... so for around town.. they do what they are supposed to do.. but they aren't reliable in the long run. If you keep the car long enough.. you will replace them again and that was one of the 2 reasons I got rid of my 07. The IMRC were deleted in later model Focus's my 09 does not have them.

Well i got the part number for them. And it will cost half what it would cost to replace the whole manifold.

I would have added a 23 motor
